This folder contains replication files for "A Field Experiment on Search Costs and the Formation of Scientific Collaborations"
By Kevin J. Boudreau, Tom Brady, Ina Ganguli, Patrick Gaule, Eva Guinan, Anthony Hollenberg, and Karim R. Lakhani, 
forthcoming in the Review of Economics and Statistics.

The following files are included in the folder:

data_preparation.do -> Describes the steps taken to generate the files dyad_ready and dyadic_ready_public from the raw data.

analysis_final_public.do -> Replicates the main results of the paper (table 4 column 1 and 2) using the data from dyadic_ready_public.dta

dyad_ready_public.dta -> Core data which can be used to generate the main results of the paper (table 4 column 1 and 2) 

analysis_final.do  -> Generates all results tables in the paper. The do file requires the dyadic_ready data file which is not included in this release (more below)  

log_analysis_final_do.smcl -> Stata log output from running analysis_final.do

All files were produced with Stata 12 running under Windows 7 or 10.

Variables included in dyad_ready_public.dta

_______________________________________________

An individual observation in the data is a pair of two researchers

x_night: indicates which night the first pair member attended (31, 1 or 2)
y_night: indicates which night the second pair member attended (31, 1 or 2)
dum_1: 1 if the two pairs members attend on February 1, 0 otherwise
dum_2: 1 if the two pairs members attend on February 2, 0 otherwise
x_room: indicates to which room the first pair member was assigned to
y_room: indicates to which room the second pair member was assigned to
x_participantidnum: an arbitrary numerical identifier for the first pair member
y_participantidnum: an arbitrary numerical identifier for the second pair member
same_room: 1 if the two pair members were assigned to the same room, 0 otherwise
same_night: 1 if the two pair members attended on the same night, 0 otherwise
any_coapplicant: 1 if the two pair members submitted a collaborative grant or concept award applicatin

Access to additional data

_______________________________________________


The terms of the Institutional Review Board (IRB) approval for the experiment preclude the public release of 
any data where any information about human subjects or their responses could be identified. 
This includes both data with personable identifiable information, or data that could support reidentification..

Access to additional data may however be granted under a Data Use Agreement which will require IRB approval. 
Researchers interested in gaining access to data for replication purposes may contact Eva Guinan at the Dana-Farber
Cancer Institute (Eva_Guinan@dfci.harvard.edu) or Karim Lakhani at Harvard Business School (k@hbs.edu)
